He is the author of innovative, internationally famous botanical publications, the exotic worldof he introduced exotic plants such as the tulip and potato world of in the Low Countries, and he was advisor of princes and aristocrats in various European countries, professor and director of the Hortus botanicus in Leiden, and central figure in a vast European network of exchanges.

S. Hitchcock, revised by Agnes Chase (1951). iii PREFACE The first part of our Annotated Checklist, covering the 2001 species of Ferns, Fern Allies, Gymnosperms, and Dicotyledons native or naturalized in the Washington-Baltimore Area, was published in March 2000. Part II covers the Monocotyledons and completes the preliminary edition of the Checklist, which we hope will prove useful not only in itself but also as a first step toward a new manual for the identification of the Area’s flora. Such a manual is needed to replace the long- outdated and out-of-print Flora of the District of Columbia and Vicinity of Hitchcock and Standley, published in 1919. In the preparation of this part, as with Part I, Shetler has been responsible for the taxonomy and nomenclature and Orli for the database. As with the first part, we are distributing this second part in preliminary form, so that it can be used, criticized, and updated while the two parts are being readied for publication as a single volume.

Key Vocabulary: Binomial name/nomenclature, Class, Classification, Common name, Domain, Family, Genus, Kingdom, Life process, Order, Phylum, Species, Taxonomy, Carolus Linnaeus’ System for Classifying Organisms Classification • Classification categorizes organisms into smaller groups. • In the same way that the books in a library are sorted according to their respective topics, science also has a way of categorizing the 1.5 million species that have been discovered so far. Carolus Linnaeus’ System for Classifying Organisms The Importance of Classification All living organisms are made up of cells and demonstrate each of the seven key life processes below: • movement • respiration These 7 life processes can be • sensitivity remembered using • growth the acronym: • reproduction MRS GREN • excretion • nutrition Carolus Linnaeus’ System for Classifying Organisms The Importance of Classification: • uses a hierarchy of levels based on the degree of similarity between species and how they carry out their life processes. • makes studying populations of organisms easier as they have many shared features. • newly identified can be placed into an appropriate group by observing how they carry out each life process.

    Originis of Mexican Malpighiaceae

    Acta Botanica Mexicana 104: 107-156 (2013) ORIGINS OF MEXICAN MALPIGHIACEAE William R. andeRson University of Michigan Herbarium Ann Arbor, Michigan 48108, USA [email protected] ABSTRACT The approximately 42 lineages of Malpighiaceae currently known in Mexico are identified and briefly described and discussed. All the Mexican lineages have their ultimate roots in South America, although in some cases the connections are inferred only through phylogeny and several Mexican genera probably originated in Mexico. All the lineages have effective adaptations for dispersal except the genus Galphimia, but distributions outside Mexico and a phylogenetic tree suggest that while many Malpighiaceae reached Mexico through “stepping-stone” dispersal, some lineages probably arrived as the result of episodes of long-distance dispersal from South America. Key words: biogeography, Malpighiaceae, Mexico, phylogeny. RESUMEN Se identifican y se describen y discuten brevemente los aproximadamente 42 linajes de Malpighiaceae que se conocen hasta ahora para México. Todos los linajes mexicanos tienen sus últimas raíces en Sudamérica, aunque en algunos casos las conexiones se infieren únicamente mediante filogenia y algunos géneros mexicanos probablemente se originaron en México. Todos los linajes tienen adaptaciones efectivas para su dispersión excepto el género Galphimia, pero las distribuciones fuera de México y un árbol filogenético sugieren que aunque muchas Malpighiaceae llegaron a México mediante el modelo de dispersión de “piedras de paso”, algunos linajes probablemente arribaron desde Sudamérica mediante dispersión a larga distancia.
